Nov 13, 2010
i have a column in a gridview with an imagebutton in a column. i added an onclientclick event so that a html confirm dialog shows with ok and cancel button, so that if you click cancel, the event should not continue, but if you click ok, the gridviews onrowcommand should fire. The grid is as follows:
[Code]....
[Code]....
but when i click the button on the grid, the alert comes up and if i select ok, i get the following exception:

I'm using a standard GridView control inside of a web form. The web form uses a master page. The application is running within sharepoint (wss 3.0) environment. When i attach both the OnRowCommand and OnRowDatabound events to the gridview as shown in the markup below, only the OnRowDataBound event fires. The OnRowCommand never gets hit. When i press a button on a row, it posts back but never hits the onRowCommand event and simply falls through and repaints the page . However if i remove the OnRowDataBound event, the OnRowCommand event starts to fires correctly. I've tried a number of things...1. Hooking up the events in code instead of markup. (inside of PageLoad or PageInit)2. Changing the order in which the events are attached.

I have something simple but for some reason it's not working.
On my OnRowCommand I am doing a DataBind but for somereason my Grid always stays blank.
I chceked in the Debug and It gets the data fine
this.GridView1.DataSource = recruitmentTemplateCandidates; // there is data here.
GridView1.DataBind();
after that it goes to OnPreRender and then nothing shows up in the Grid. why is that?

I have a gridview and I have a link button that fires the onrowcommand event. In the method I have
protected void SelectCreditCard(object sender, GridViewCommandEventArgs e)
{
int index = Convert.ToInt32(e.CommandArgument);
}
But I get the error input string in incorrect format.

I have a webpage with many updatepanels. Each panel contains databound controls including gridviews (GV). They are bound at runtime so the number of gridview columns varies with each bind. the controls are bound only once in Page_Load event ( within if (!Page.IsPostBack) )I added a linkbutton to each header in the GV in the RowDataBound event. Once the header is clicked, the event is handled in the OnRowCommand and it calls a method to bind the controls with new data.Things work fine if the GV is bound with every postback (no if (!Page.IsPostBack) condition) but I don't want to bind all the controls with every postbackMy problem is that the OnRowCommand is not fired if the GV is not bound on the postbackI even tried to add click handler for the linkbutton but that didn't work either.

I've following gridview:
<asp:Panel ID="pnlScroll" runat="server" ScrollBars="Auto">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
[Code]...
Now I am not able to understand why the OnRowCommand event is not firing. Nothing is happening on clicking the button in gridview.

I have a gridview with a template column that causes a postback on check changed in order to change display. It works fine:
[Code]....
And the code behind:
[Code]....
Works great, right? Well I wrote a small javascript file to make the checkboxes mutually exclusive, but now, while the post back refreshes and the javascript works, it does not show the popup extender anymore - it doesn't even enter the codebehind function.

Why doesn't my "return confirm ()" work in my gridview template control ?
When I click on select the row the onclick event happens but the OnClientClick never happens.

I have an image button in my gridview which I'm using to open a new window.
The code for my image button is:
[Code]....
This works fine, in that a new window is opened correctly, however, clicking the button causes a blank row to be added to the top of my grid.

I have a GridView with a couple of buttons (asp:Button) in it (last row). Both of them have a CommandName attribute on them and this is handled server side in a grid_RowCommand event handler. Now, this works fine. However, I need to add client side code (Javascript/jQuery) to disable the two buttons when someone clicks on or the other. This is to prevent the user from double-clicking and creating potential havoc.
The way I have done this is by adding OnClientClick on both buttons which calls a javascript function that uses jQuery to disable the two buttons. This works fine, it's just that the page doesn't post back and so the RowCommand event handler never fires.

how to get the SelectedDataKey.Value when you have a button on your gridview that does not have the commandName="Select"? I already have the custom gridview select that have the commandName="select" and it works great to get the selected value and show my detailsview from the row selected. Now I want another button on my gridview that does a completely different action and actually does a page redirect, I just need to get the actual SelectedDataKey.Value only I made the commandName="View" or just something different from select becuase I don't want it to follow the same actions and event as select does.
Here is my .cs

I have a gridview that I am using to host some data. Each row in the gridview links to a blob and I am using the SOnRowCommand event to click on the row and to stream the blob(which is an image) out as a file. This works fine. However when i implement paging on the gridview with the paging event the handler think it is an OnRowCommand event and executes the code behing the OnRowCommand handler and not the pageindex change event.
[Code]....
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
DataTable dt = new DataTable();
dt = (DataTable)Session["data"];
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataSource = dt;
GridView1.DataBind();
}

I'm using the OnClientClick to return the confirm message box. This is what i have so far:
[Code]....
I want to be able to pass one of the fields to it, such as a name, to enhance the confirmation. I want it to be more informative by adding the product or customer name. This should make it read more like this "Are you sure you want to delete the customer Jones?" I suspect I will have to use the {0} but don't understand what I will need to do to get this to work.

I have a page for a product listing using a datalist control. I have customized the item template and added a link button that says Click to Order. I then databound that linkbutton with the onclientclick to the "ProductID" field, but I would like to set a variable or use some method of getting the productID of which item they clicked so I can add that product to an order. I cannot understand how to find out which item was clicked though... here is my code:

I want to display a warning message and then open a panel on my form in response to a button click in my gridview.
I have used this on another form with a delete command in a gridview column and it work perfectly.
Why isn't it working with my select command ?
Here is the code:
<asp:LinkButton
ID="LinkButton3"
runat="server"
CommandName="Select "
OnClientClick
=
"return confirm='Are you sure that you want to delete this record ?');">Select</asp:LinkButton>
</ItemTemplate> </asp:TemplateField>

I have a button inside my <ItemTemplate> in GridView and I want to call a javascript function on the OnClientClick of that button passing the DataItem value as a parameter of the javascript function
[code]....
If I will not put a parameter in CreateEditAddess() this works well but I need the parameter.
I know I can put the OnClientClick event value in OnRowDataBound event of the gridview but I don't want to put it in CodeBehind. It seems like the server tag is not parsed correctly.
